When hand pain occurs the next day after lifting heavy objects, it is usually due to the excessive weight of the heavy object being moved, which exceeds the normal bearing range of the hand muscles, and a slight strain or a strain injury is formed due to excessive fatigue of the muscle tissue as a result of lifting for too long. During the lifting process, the blood circulation is faster, the bruises and metabolites produced are not easy to accumulate, so the symptoms are not obvious, but after resting, the blood circulation decreases, especially when the hand is cooled during rest, which leads to local vasoconstriction, so the metabolites produced cannot be metabolized through adequate venous return, and the accumulation of metabolites is more, so it is easy to The accumulation of metabolites is more likely to stimulate the peripheral nerves and cause hand pain the next day. After this situation, it is necessary to keep the hand muscles and surrounding soft tissues relaxed, avoid continued force, apply a warm water bag or hot water for scalding, scalding process of appropriate movement of the hand, can accelerate circulation, help relieve the symptoms of pain and promote recovery.
